Researchers also looked at male infidelity and found that men have a less specific window — specifically, they found that men were more likely to commit adultery after 11 years of being in a relationship.

These findings were revealed after researchers conducted two surveys involving 423 people. Each of these participants completed a survey on the perceived importance of resisting the temptation to cheat. They also answered questions on how likely they would cheat given the opportunity.

That study also found that men who are tall, smart, and wealthy are more likely to be unfaithful because their cheating is driven by ego and lust, as opposed to loneliness.

And despite the finding that women cheat in a specific time frame of their relationship, multiple studies suggest that men cheat more than women, as women are socially conditioned to cheat far less.

"Women are known to be more sensitive to social pressure than men and there has always been more pressure on proper sexual behaviour on women," Michèle Binswanger, a Swiss journalist and author of Cheating: A Handbook for Women, told The Independent.

"Also they traditionally had fewer opportunities because they were more likely to stay at home with the kids," she added.

Women are known to be more sensitive to social pressure than men and there has always been more pressure on proper sexual behaviour on women.

Binswanger's insight also confirms what previous studies have suggested, which is that women's thoughts about what a successful, meaningful relationship should look like have changed.

"Today women have higher expectations about their sex life than 40 years ago, they want to experiment and are generally more independent," Binswanger said, adding that most women who cheat on their partners not only feel frustrated with their relationship, but with their lives in general.

"Many felt undesired, unheard or just unhappy, so they started looking for excitement," Binswanger noted.
